Liquid simulation on MacOS

[neilwth]

After pulling the latest src with this PR, the float32/64 issue resolved, but I still got the following issues with backend gs.metal:

[Genesis] [11:36:48] [WARNING] pbs sampler failed. Falling back to random sampler.

and

[Genesis] [11:36:58] [INFO] Compiling simulation kernels... RHI Error: cannot create compute pipeline state: Compiler encountered an internal error (code=3) RHI Error: cannot create compute pipeline state: Compiler encountered an internal error (code=3) Assertion failed: (p != nullptr), function bind_pipeline, file metal_device.mm, line 382.

Still, the script works fine but slowly with cpu, and simulations without liquid are OK for both cpu and metal.

Met same problem.

same issue here. Works with cpu but not with gs.metal backend

Are you saying you SAW sth / the Viewer on the Mac? Guess no.

I commented out this line and it worked.

Genesis/genesis/engine/solvers/rigid/constraint_solver_decomp.py line 840: self.efc_force[i_c, i_b] = -self.efc_D[i_c, i_b] * self.Jaref[i_c, i_b] * self.active[i_c, i_b]
